such as'automobiles.

, l The lchiefobject ofimy present improve-r ments is to 4produce aisafe, simple, conven.l -ient, reliable andinexpensive device adapted to preslect the gearintendedfto beshifted intomeish with` anothergea'r for the purpose 'if transmitting the powerrof the 'driving means, such as a motor, to-the driven means,A 'such asa vehicle, the devicebeing ac lapted` lto prei-entfthe shifting of gears while the driving means are connected with the driven means, to prevent the shifting of one of the ,gears into mesh before another 'ear is shifted out of mesh, to indicate onsecufj tivelythe neutral positions Gf all the gearsj and the speedl changing positions of each gear, and to vprevent the transmission of power to the driven means before a gear has been properly shifted.

' The gchief object is to provide a selector adapted to preselect andtoindcate a change in the-speed of a variablespeed machine, suchI as an automobile, which meansare controlled manually and areV operated' purely mechanically i without the intervention of any electrical, magnetic or electro-magnetic means..

lWith-4 the above andv related objects in view, my present` invention comprises'the hereinafter described constructnm, ,combinesI tion and arrangement of parts,- as illustrated vline 3 3 ofFig. 4; Fig. '4 is in the accompanying drawings, and which arefembraeed within', the scope of the appendedclaims.

In the said drawingsfFigurel is a dia-' grammatie 4view of a gear box suspended from the foot board of an automobile and revidexl with my. improved gear selector; ig. 2 is a plan view of'my improved indicator orcontroller; Fig. 3 is a section on the section on the line 4-4'of' Fig. 3; Fig.l 5 1s a section onV the4 line 5-5 of Fig..3; Fig. 6 is a section on the line 6-6 oi Fig.,3, and Fig. 7 is a sec- "tion on the line' 7-7 of 3.

i Referring Vmore particularly trethe drawing for a. detail description of my inven- Ation :.-1, re Vresentsa flat ring carried by a, hub 2, whc constitutes the bearing for the customary steering wheel 3. As shown in Fig. 2, half of `the ring 1 is of uniform diameter, while-the other half is provided with 'peripherally" alternating concentric. eleva# tions and depressions, the 4depressed portions being cent-rally provided with notches marked R, 1, 2 and 3, and the elevated portions with' similar notches marked N. 1 rep- `res'entsa1shaft,`shownf to be projected through' the "hub f2 and through the foot board of'th'ejvehicle', below which it is supported by abearingof a bracket 6'. On' top 'of the shaft ismounted' a crank lever T,

wwhich' is ,bentj and' extended from' under the ring, or indicator 1 and a't `right angles with `1ts periphery.where it is providedwith a adapted to bearagainstsaid periphery.

jected, the projecting' end carrying one of a -Y pair ofl bevel gears 14, the other one being -mounted on the shaft 4. ,Thc opposite end of the shaftl carries a bevel gear in mesh with a similar gear 15 mounted onl the selecy tor shaft 16.` 4 Bnul -and BH represent apair,

of bars projecting `rearwardly of `the casing 11 and within the gear box ll'whe-re each provided with a shifter 18.

19 represents a sh ft, supported a bearmg 20 of the gear box," said shaft being adapted to transmit-the power of a. motor (not shown) -to a, shaft 2l supported by a bearing 22 of the box and adapted to drive v'the vehicle. The portion of the shaft 21 in,- side the box 1'7 is shown to be square faced and adapted to slidngly support 'the Af .geers B -l andV 2 3 which are mounted to rotate 'with'said shaft. The gear 2--3 is provided with face teeth adapted to become inter` roo locked with those of the gear'g. The box 1'1Y is also provided with bearings for a countershaft 23, which carries the gears g, g, r1.2

and 24, and with a bearing for an idler shown to be in mesh with the gear gn. The gear 24, which is shown vto be in mesh with the gear g", is adapted to transmit the Amotion of the driving shaft 19 to the counter shaft 23. The idler, which is drivenby the gear g", is adapted to transmit the motion of the countershaft to the driven shaft 21 when the gear R--l is shifted to mesh with said idler in a direction opposite to that of the shaft 19 and at a reduced speed. The gear g1, when the gear R-1 is shifted to mesh therewith, is adapted to transmit the motion of its countershaft to said shaft 21 in the dircction of the shaft 19 but at a reduced s eed. The gear/y2, when the gear 2-3 is shifted to mesh therewith, is' adapted to transmit the motion of its countershaft to the shaft 2l in the direction of the shaft 1f) at an intermediatc speed. linen said gear 2 3 is shifted to vbecome interloeked with the 'gear g, the shaft 21 is driven in the direction and .with the speed of the shaft 19.

(ln the shaft 16, inside the casing 11, is mounted an interlock 25, said interlock comprising a pair of disks provided with peripheral recesses 2G located as'shown in Fig. 5. 26 The casing 11 is provided with a perforated partition 27 .pivotally supporting the levers 28 111(1'28l whose fulerums are in opposite alinement and the levers 282 and 28"s whose fulcrums are also in opposite alinement and 30 parallelwith the first above mentioned' pair of 1evers. The" levers are adapted to ride with their free ends 29 upon the' peripheral surface-of the interlock, each'V painbeing. yield'ably' connected by a springO. *Each a6.lever is provided' with a 1u 31,;adapted to project through a eorrespo ng perforation of thepartition27.A V Inside the casing 1 1 are mounted racks 32 and 33, eachgrack being in mesh with a pin- 40 ion 34 adapted actuate saidy racks in opposite directions. he rack 32 is-providedwith a pair of carrie rovided :with a. similar pair of carriers 37.

tach paifof carriers is jied transversely 'by a rfid 38, the opposite ends of each rod Intended tovproject through the slots '-'bars B"1 and B21. \O n the opposite f each rod and spanning each bar are `umed pawls 'provided with hooks re' spectirely designated as 39", 391, 392 and 139.

The hooks 39 and 391 are adapted to become respectively engaged with the opposite shoul- ,ders of the central recess of the bar BR, and f ,the hooks 392 and 39 are adapted to become 'i M irfsimilarly engaged. with the'bar lF-.

46 represents a slide carrying a. pin 47,'and 48 'represents a' lever having oneof'its'ends f ulcrumed on said pm 47 and yieldabl y connected with theislide by a spring 49 wound on the pin. The lever 48 terminates in a, lug adapted to beaetuated by the spring 49 to yieldably bear against the. cam surface of aplateO. l'

The slide 46 is provided with a rectangular extension adapted to bear'ag'ainst the abutting end of the rack 32and is connected with u ro'd 51 which is projected through a. bearin 5 2 in frontof the casingll.

In escribing the operation of my im# proved' speed selecting indicator, it is assumed, as shown in Fig. 1,l that the driven 'ont of mesh an'd disconnected from the transmitting elements 47", ,'g and r/. It is also assumed that it is intended to reverse or start .rearwardly,`as is indicated by the posi-v tion of the handle 8, in alinement with the position marked-R-jon theindicator 1, as Slnfwn'intFig. I

Referring to Fig. 3 that thehook 'p'awl 39n of thef b ar .B R an adjacent".shoulderl 'Referring .to Fig'. 4,' it vwill bexzobserved th I, it ivillibe observed isdown upon 4the 1 e di is engaged with' an shownto be.' .itsextremeffrontwrd osiv tion,"' ridth of the lever-"48 -is in a ine' ment vgitlfthe' high "surfaceiofgthe' cam plate ljlfe'the rack`33 is in yitsi-extreme rear .spo-sfido. l efer'ri'ng to Fig. 5 `that"tl1e fme. end of the lever -28R is down'y upon' one off the recesses 26 of the interlock. Referring to Fig. 7, it will he 'observed that :the l-ug'3l of saidlever 285 in 'positont'o ride on top of the pawl hook 39 From the ahove it. will he understood that, if the rod ."1 he forced rearwardly, the slide4 46 will'foreethe rack 32 withA its carrier's 36 rearwardly, and the pinion 34 will -force the. ruck with its carriers 37% frontwardl v.

- Asthefpawl hooks are normally held in their elevated positions by the springs 44,-they do not transmit anyr Amotion to the shifter bars I engage the bar TSR1v hy the lug of -the leverf gon top of said pawl hook. The. rearward movement -o'f the curriers-36 will thus he. transmitted to 1the bar 12""1 to cause its shifter 18 to force 1e gear R-l ingmesh v with'tlie idler of the 'ear g. I; The ex'triane' rca-r and movementv of the rod 51 Ais made to coi eide 'with the position ofthe shifted gearw nfjt is properlyinmeshI with the trans-mi ftinj' ar, andI corresponds with the extrem .f1-e" ward movement of the rack 32 with 'its pziiltllgearriers 36" 4actuated "180 it will be obseved-f 1 nio which is forcedto' l ,bytheslide 46', and with the estreme frontward movement of the rack 33 with its pawl -carriersw37 actuated by the inion 34 which causes said rack 33 to move rom its position under1 the cam plate 50 indicated by the dottedi line and frontwardly past the hook of the lever 48. y

When the movement of the rod 51 is reversed, the slide 46 ismoved away from the rack 32 and the lever 48 'is carried frontwardly with its hook sliding along the rack 2l i fromthe sh aft et to theshaft- 13 by the gears V33 until it is 'ust ahead of said rackv when it is actuated y the spring 49-.to hook onto said rack. This corresponds ywith the ex tremecfrontward movement of the rod 51,

l`and during this movement there is no change "in the relative positions of the shifter bars.

Assuming now that the crank .T is turned fromits osition R on the indicator to the position this movement is transmitted 14, and from the shaft 13 to the shaft 16 by the gearsV 15 to cause'the interlock to rotate in the direction of the arrow. During/this movement, the free end of the lever 28,, is'` forced out of the recess of the interlockA and onto the cylindrical periphery thereof, whereby said lever is caused toi .swing Vin a direction away from its-adjacent 'lever 2.8,?, and its lug 27' is forced off the topof its pawl. The pawl39Rv is` thus re-v "leased and its, spring 44causes it to swing with its hook off the shoulder of the bai?, B'ivf the ro'd 51 be now moved rearwardly,

then during the first half of its said rearward movement the rack 33 is-actuated bytheJ hook-ot the lever 48 to move with its pawl'carriers into itsextreme rearward position, in which posit-ionA the `cam plate 50. .forces said lever to release the rack, and

" the rack 32 is actuated by the pinion 34 to move with its pawl 'carriers into its eXtreme irontward position in which position it is incontact with the sideof the slide 46.

'During the 4aforesaid movement, the bar "BFM, is forced to move from its extreme rearwardjposition into a central position by the rod of the carriers 36, and the gear, R-l is forced out of mesh with the'idler of the into a neutral position `in theidirection of the geargl. During the` last halfof the rearward ,movement of the rod-3.51., the direction of motion ofthe racks isre'versed, and as Ythe hooks of the pawls are" not. engagedv` with any, of the shifter fibers-said bars are not disturbed and the gearsremain in a neutral position.

.The movement of' the crank? into the position marked 1 coincides 'with the movemen-tof the'interlock which'brings one of Uits rei''esses under the free end of the lever 28, which freeend'is forced into it by the y spring connectingits leven with -`the lever 28', andthe swing of the 98x inthe direction, of the lever 28 causes the-lugof the lever 281 to ride on top ofv the pawl 391. From the above it will be understood that, with the selector handle inthe aforesaid position, the gear R-l is shifted from its neutral position in to Vmesh withthe gear g1L during the last half of the rearward movement of the rod 51.`

From the above description of the operation of the device, it will be readily understood that, when the selecting handle is l moved from the indicated .position 1 into an indicated position N, the gear, lts-1 is moved out of mesh with the'gear g1 during the first half of the rearward movement If, however, the selectingV of the rod 51. 4 l handle be moved into the indicatedposition 2, the interlock will be moved with one of its recesses in alinement with the free-end of the lever 282, and the spring connecting said lever with the lever 28R will force the d lug of the lever 282 on top of the pawl 39z und cause it to swing with its hook down the recess of thebar Bza, and during the last half of the rearward movement of the rod 5,1, the' said bar will be moved'rearwardly and its shifter 18 will force the gear 2-3` into mesh with the gear g2.

If the selector handleis movedinto the indicated position 3,' the 4interlock first forces'the free end ofthe lever 282 out of its recess and subsequently permits thefree end of the lever 2B3 to enter ari-'adjacent recess, so that the pawl 392' is released and the pawlr393 is restrained by the lug ofthe lever 283. If the rod 51 be nowmoved rearl wardly,then during the first half of said.

rearward movement the'bar B24 is actuated to move frontwa'rdly by the rod of the car- 7 riers 36 to force the gearV 2-3 out of mesh with the gear-.9, and during'the last 'half of'said rearward movement the same` bar is actuated by the pawl hook 39a toicontinuev l in-itssaid frontward movement and to force said gear 2*-3 to become connected with the gear g3.
